Quartz Capillary Tube Overview
Quartz capillary tubes are precision quartz glass tubes characterized by small outer diameters and fine inner bores, widely used in laboratory, analytical, and industrial systems where controlled flow, sampling, or optical transmission is required.
Compared with standard quartz tubes, capillary tubes require tighter dimensional control, especially on inner diameter (ID), concentricity, and surface quality. These parameters directly affect flow stability, pressure response, and measurement accuracy in downstream applications.
At GlobalQT, quartz capillary tubes are produced from high-quality quartz glass and processed using dedicated capillary drawing and precision finishing techniques. We supply a wide range of OD / ID combinations from regular inventory, with consistent dimensional repeatability suitable for both prototyping and series use.
In addition to standard stock sizes, custom capillary tubes can be manufactured based on drawings or specific technical requirements, including special inner diameters, cut lengths, tighter tolerances, and secondary processing when required.
Applications of Quartz Capillary Tubes
Quartz capillary tubes are widely used in applications where precise micro-scale flow control or accurate internal dimensions are required. Typical applications include:
Scientific Instrumentation & Analytical Systems
Commonly used in spectroscopy, chromatography (GC / CE), and various analytical and testing instruments, where consistent inner diameter and surface quality are critical.
Microfluidics & Precision Fluid Control
Applied in microfluidic systems, small-volume sampling, and precision fluid transfer, providing stable and controllable micro-scale flow channels.
Electronics & Medical Analytical Devices
Used in electronic components and medical analytical instruments that require high dimensional accuracy, material stability, and cleanliness.
Optical & Laser-Related Components (Selective Applications)
In certain optical, laser, and precision glass assembly applications, capillary tubes may serve as structural or functional components.
